Edit Control Message APIs for Windows X. h

Generally, you need to convert the ID defined in resource to hwnd. The most common function is the getdlgitem () function!

When writing the SDK program, you must obtain the content in the editbox. There are multiple methods:
Here I will introduce two topics:
1. Use getdlgitemtext
Eg:
Getdlgitemtext (hwnd, idc_edit_oldname, szoldname, max_path );

2. Use the macro edit_gettext (hwndedit,) in windowsx. h ,,,)
Here we need to convert resourceid to hwnd
Eg:
Edit_gettext (getdlgitem (hwnd, idc_edit_oldname), szoldname, max_path );
